SEM & EDX Analysis in Chennai: Advanced Material Characterization by Tamilnadu Test House

In today’s rapidly advancing industrial and research environment, understanding the composition and structure of materials at the microscopic level has become essential. Tamilnadu Test House , one of the leading testing and analytical laboratories in Chennai, offers SEM analysis in Chennai and SEM EDX analysis services to support industries, researchers, and manufacturers in obtaining precise and reliable material characterization results. What is SEM & EDX Analysis? Scanning Electron Microscopy (SEM) is a powerful technique used to examine the surface morphology and microstructure of materials at high magnification. SEM provides detailed, three-dimensional-like images of a sample’s surface, allowing scientists and engineers to observe features that are not visible under traditional optical microscopes. Energy Dispersive X-ray Spectroscopy (EDX or EDS) is often combined with SEM to analyze the elemental composition of the sample. Together, SEM EDX analysis offers both morphol...

Reliable Soil Testing Services in Chennai: Ensure Healthy Crops & Sustainable Growth with Tamilnadu Test House

Soil is the foundation of agriculture, and its health directly determines crop yield, quality, and sustainability. However, continuous farming, use of fertilizers, and industrial activities can alter soil composition, affecting its fertility and productivity. This is where soil testing becomes crucial. At Tamilnadu Test House , we provide accurate, reliable, and scientific soil testing services to help farmers, agricultural institutions, and industries understand their soil better and make informed decisions. Importance of Soil Testing Soil is not just dirt—it is a complex mixture of minerals, organic matter, water, and air that supports plant growth. Over time, soil nutrients get depleted, leading to reduced productivity. Excessive use of fertilizers without proper knowledge also causes nutrient imbalance and environmental pollution. By conducting soil testing, one can: Identify nutrient deficiencies and imbalances. Understand the soil’s physical and chemical properties. ...

AYUSH Testing Lab: Ensuring Quality and Safety in Traditional Medicines

At Tamilnadu Testhouse, one of the leading food testing labs in Chennai , we specialize in delivering precise and reliable shelf life studies that help businesses enhance product quality, extend longevity, and build consumer trust. Why Food Shelf Life Testing Matters Food Shelf Life Testing goes beyond checking expiration dates. It involves a scientific evaluation of how long a food product maintains its safety and desired qualities under specified storage conditions. Factors such as microbial growth, chemical changes, texture, flavor, and nutritional value are studied to determine the true shelf lif...

Understanding Total Polar Compounds in Oil: A Key Indicator of Oil Quality and Safety

In the food and oil processing industry, maintaining the quality and safety of edible oils is crucial. One of the most significant indicators of oil degradation during use, especially during frying, is the formation of Total Polar Compounds (TPCs) . These compounds play a vital role in determining whether the oil is still suitable for consumption or needs to be discarded. What Are Total Polar Compounds? Total Polar Compounds are a group of substances formed when edible oils are exposed to high temperatures, such as during deep frying. Over time, heat, oxygen, and moisture cause the oil to break down, resulting in the formation of polar substances like oxidized triglycerides, free fatty acids, mono- and diglycerides, and polymerized triglycerides. These compounds increase with repeated oil use and indicate oil degradation, reduced nutritional value, and the potential formation of harmful substances. Why Is TPC Measurement Important? Monitoring TPC levels is essential for both food safe...

Indole Test in Microbiology... #science #chemistry

Indole Test Procedure: Inoculation: Using a sterile inoculating loop, transfer a loopful of the bacterial culture into a tube of peptone water or tryptophan broth. Incubation: Incubate the tube at 35–37°C for 24 to 48 hours. Addition of Reagent: After incubation, gently add 5 drops of Kovac’s reagent down the inner wall of the test tube without shaking. Observation: Allow the tube to stand undisturbed for a few minutes. A red or pink ring at the top indicates a positive indole test. No color change indicates a negative result. 🎯 Why is the Indole Test Important? Helps identify indole-producing bacteria Used in medical and clinical diagnostics Commonly applied in water and food safety testing #IndoleTest #Microbiology #ScienceExperiment #ChemistryLab 

Membrane Filter Method.... #sciencereels #analyticalchemistry

The Membrane Filter Method is a widely used microbiological technique for detecting and counting bacteria in water and liquid samples. 🔬 Procedure :  Take a measured volume of the sample (usually 100 mL). Pass it through a sterile membrane filter (0.45 µm pore size) using a vacuum pump. Place the filter carefully onto a selective agar plate. Incubate the plate at the required temperature (typically 35–37°C) for 24–48 hours. After incubation, count the colonies that have grown on the filter surface. Calculate the result as CFU per 100 mL of sample.
